Hi,
first you define a list of functions of 3 arguments, e.g.:
f={
#1+#2+#3&,
2#1+#2+#3&,
#1+2#2+#3&,
#1+#2+2#3&,
2#1+2#2+#3&
};
then you make a list of arguments, e.g.:
x={
{0,0,0},
{0,0,1},
{0,1,0},
{0,1,1},
{1,0,0},
{1,0,1},
{1,1,0},
{1,1,1}
} ;
now we apply all functions to all arguments:
Outer[Apply, f, x, 1]
hope this helps, Daniel
